Why This Recipe Works
The structure of strawberry swirl fudge relies on:
- Sweetened condensed milk → Provides sugar and milk solids for smoothness
- White chocolate → Sets firmly when cooled
- Butter (optional) → Enhances creaminess
- Strawberry flavor component → Adds color and fruit brightness
White chocolate contains cocoa butter, which solidifies as it cools, giving fudge its firm texture without traditional sugar boiling methods.
Ingredients (Makes 25–36 Pieces)
Base Fudge
- 3 cups (510 g) high-quality white chocolate chips
- 1 can (14 oz / 397 g) sweetened condensed milk
- 1 tbsp unsalted butter (optional but recommended)
- 1 tsp vanilla extract
- Pinch of salt
Strawberry Swirl
- ¼ cup strawberry jam (seedless preferred)
OR - 1–2 tsp strawberry extract + pink food coloring
Equipment Needed
- 8×8 inch baking pan
- Parchment paper
- Heavy-bottom saucepan
- Spatula
- Toothpick or skewer (for swirl)
Step-by-Step Instructions
1. Prepare the Pan
Line an 8×8 pan with parchment paper, leaving overhang for easy removal.
Lightly grease if needed.
2. Melt the Base
In a saucepan over low heat, combine:
- White chocolate chips
- Sweetened condensed milk
- Butter
Stir continuously until melted and smooth.
Important:
Do not overheat. White chocolate scorches easily.
Remove from heat.
Stir in vanilla and salt.
3. Pour into Pan
Spread evenly in prepared pan.
Work quickly before it begins to set.
4. Add Strawberry Swirl
Warm strawberry jam slightly (10–15 seconds in microwave).
Drop spoonfuls across surface of fudge.
Use a toothpick or knife to gently swirl.
Do not overmix—you want distinct marbling.
5. Chill
Refrigerate 2–3 hours until fully set.
Lift out using parchment.
Slice with warm, clean knife.
Achieving the Perfect Swirl
For a clean marbled effect:
- Add jam in small dots, not large pools
- Drag toothpick in figure-eight motions
- Stop when pattern looks defined
Over-swirling blends colors and reduces contrast.
Texture Troubleshooting
| Problem | Cause | Fix |
|---|---|---|
| Grainy texture | Overheated chocolate | Melt gently next time |
| Too soft | Too much jam | Reduce swirl quantity |
| Oily surface | Chocolate overheated | Lower heat |
| Won’t set | Incorrect ratio | Use full 3 cups chocolate |
Jam vs Extract: Which Is Better?
| Option | Result |
|---|---|
| Strawberry jam | Natural fruit flavor, softer swirl |
| Strawberry extract | Stronger flavor, cleaner texture |
| Freeze-dried strawberry powder | Intense color + real fruit |
For premium results, use freeze-dried strawberry powder blended into a small portion of fudge.
Flavor Variations
White Chocolate Raspberry Swirl
Replace strawberry jam with raspberry preserves.
Chocolate Strawberry Fudge
Add ½ cup dark chocolate chips to base.
Strawberry Cheesecake Fudge
Add 2 oz cream cheese to base (reduce butter slightly).
Valentine’s Sprinkle Topping
Add heart sprinkles before chilling.
Storage Guide
| Storage | Duration |
|---|---|
| Refrigerator | 2 weeks |
| Room temp (cool climate) | 4–5 days |
| Freezer | 3 months |
Store in airtight container.
Separate layers with parchment paper.
Cutting Clean Squares
For professional presentation:
- Run knife under hot water.
- Wipe dry.
- Slice in one clean motion.
- Clean blade between cuts.
This prevents smearing.
Why Sweetened Condensed Milk Is Used
Unlike traditional fudge that requires boiling sugar to soft-ball stage, condensed milk:
- Eliminates need for candy thermometer
- Reduces crystallization risk
- Ensures smooth texture
- Simplifies process
It makes this recipe beginner-friendly and reliable.

Make It Less Sweet
White chocolate fudge is naturally sweet. To balance:

- Incorporate freeze-dried strawberries
- Add 1–2 tsp lemon juice to jam before swirling
Common Mistakes to Avoid
1. Using Low-Quality White Chocolate
Cheap chips may not melt smoothly.
2. Overheating
White chocolate seizes easily.
3. Adding Too Much Strawberry Jam
Excess liquid affects setting.
